In this paper, we show investigate the effect of the visual cues to the tactual motion. We found following two facts. 1) Subjects tried to give a constant normal force independent on the texture provided the object is visible. 2) There are two ways of touch when it is invisible. One strategy is to give a stronger normal force to an object than that of the visible situation. The applied normal force is different depending on the texture. The other strategy is to give a constant force to an object. In this case, the applied normal force is weaker than that of the visible situation. Since there are two tendencies for touching an object under the invisible condition, we should take these features into consideration when we design the psychophysical experiment. Moreover, these insights can be used to optimize the surface condition of touch panel devices to improve the usability.
